- Braces are mandatory for all control flow
- Indentation should be kept to a minimum
- Empty lines should be placed between different kinds of statements:

int t;

assert(io->bufuse > 0);
assert(io->bufuse <= io->bs);

if ((t = write(io->fd, io->buf, io->bufuse)) < 0) {
	io->error = errno;
	t = 0;
} else if (t > 0) {
	memmove(io->buf, &(io->buf)[t], (io->bufuse -= t));
}

io->bytes += t;
io->prec  += (t > 0 && io->bufuse > 0);
io->rec   += (t > 0 && io->bufuse == 0);

return io;

- Cases in switch statements and matches in match statements should be indented
  one level
- In C, spaces should be placed in control flow statements after the keyword and
  before the opening brace:

for (i = 2; i < argc; ++i) {

- If a function, a C control flow statement, or a Rust macro has arguments that
  cause the statement to be broken into multiple lines, this should be done by
  placing the arguments on a new line inside the parentheses: 

let usage = format!(
	"Usage: {} [-d delimiter] index command [args...]",
	argv[0],
);

- If Rust function arguments or fields are on their own lines, they should
  always have a trailing comma.

- If text is on the same line as a brace, spaces should be placed after an
  opening curly brace and before a closing one:

use sysexits::{ EX_DATAERR, EX_IOERR, EX_UNAVAILABLE, EX_USAGE };

- If a control flow statement is short enough to be easily understood in a
  glance, it may be placed on a single line:

if (!argc < 0) { usage(program_name); }

- If a do while loop in C is longer than ~25 lines, place the while statement
  in a comment after the opening brace:

do { /* while(count == 0 || --count > 0); */
